Parameter description

**Table 1** Parameter description
Name	Mandatory	Description
project_id	Yes	Specifies the project ID of a tenant in a region.
instance_id	Yes	Specifies the instance ID, which can be obtained by calling the API for querying instances. If you do not have an instance, you can call the API used for creating an instance.
start_date	Yes	Specifies the start time in the "yyyy-mm-ddThh:mm:ssZ" format. T is the separator between the calendar and the hourly notation of time. Z indicates the time zone offset. CAUTION: The start time is 31 days earlier than the current time.
end_date	Yes	Specifies the end time in the "yyyy-mm-ddThh:mm:ssZ" format. T is the separator between the calendar and the hourly notation of time. Z indicates the time zone offset. Only error logs generated within the last month can be queried. NOTE: The end time cannot be later than the current time.
node_id	No	Specifies the node ID. For details, see Table 8. If this parameter is left blank, all nodes in the instance can be queried. Nodes that can be queried: mongos, shard, and config nodes in a cluster instance. All nodes in a replica set or single node instance.
type	No	Specifies the statement type. If it is left blank, all statement types are queried. Valid value: WARNING ERROR
offset	No	Specifies the index position. Its value range is [0, 1999]. If offset is set to N, the resource query starts from the N+1 piece of data. The value is 0 by default, indicating that the query starts from the first piece of data. The value cannot be a negative number.
limit	No	Specifies the number of resources to be queried. The value ranges from 1 to 100. The default value is 10, indicating that 10 records are returned by default. NOTE: The sum of limit and offset values must be less than or equal to 2000.
